  • Torque measurement circuit
    Patent number: 4979398
    Abstract: A direct acting circuit through which the torque to which a shaft is being subjected is measuring without the need for divisions or other computer assisted computations. The system is self-clocking and counts speed dependent pulses generated by shaft rotation alternately in incrementing and decrementing modes with the difference being indicative of the torque. The count may be averaged over one or more complete shaft rotations to reduce or eliminate errors due to shaft or rotation sensor irregularities.
